My invention relates'to alarm devices for baling presses and operatingto indicate to an operator of a press that suflicient material has beenfed into the press to form a bale,

and the object of my invention is to provide a device of this character,readily mountable upon a baling press, simple in construction andeffective in operation.-

7 Referring to the drawings in which similar numerals indicate identicalparts Figure 1 illustrates the application of my device to a balingpress; 1

Figure 2 is an enlarged view of my invention showing the parts as set*for operation with part of the bell broken away; 1

Figure 3 is a front elevation of Figure 2 with part of the bell brokenaway; and, 1

Figures 4, 5, 6 and 7 illustrate the various positions assumed by thetripping lever in operation.

The part of a baling press shown,- to illustrate the application of myinvention, is part of abaling chamber 1, of a well known type andconstructed of angle steel bars 2, and flat 5 bars 3, and having sidessufficiently open to accommodate theoperation of tying the bale. Part ofa finished bale 4c is shown and also part of a bale 5 in process ofbeingformed, and separating them is the division block ,6

provided with the usual grooves 7 through which the binding wire is fed.7

My device comprises a support Shaving upper and lowerhorizontallydisposed parts a and b spaced apart to form a horizontalslot 9'to receive the horizontalflange of the angle frame bar 2 andtheflat bar 3 resting thereon. A bolt 10 secures the support rigidly inplace. Extending upwardly from the support, and integral therewith, isan arm 11 the upper end of which isbent, as atf 12, to

form a seat for a bell 13 'rigidlysecured on the seat by a bolt-14 and anut on the end of the bolt. A similar arm 16 extends upwardly from thesupport parallel withthe' arm '11 and of lesser length, and between thearms Hand 16 a clapper lZis pivotally supported on a bolt 18 whichpasses through'both arms and the clapper and is securedby a nut19.

A bolt 20 extendsfrom the closed end of'the slot 9 througha suitableopening" in a boss 21 integral with the support 8, and on this bolt alever 22 is pivotally mounted, intermediate its ends, and held thereonby a nut 23. The lever is bent below its pivot and from the bend extendsdownwardly parallel with the side'of the press. Pivotally mounted on abolt 24 in the upper end "of the lever 22 is a swinging dog 25having-its upper end beveled downwardly toward the clapper l7 and inconstant contact therewith. The dog 25 is elongated below its pivot intoa narrow part 26 which is in normal contact-with the nut 23 on'the bolt20.- A coiled spring 27 has one end attached to the end of the bolt 20and the opposite end attached to an end of theclapper 17. The strikingend of the clapper 17 projects slightly beyond thebell 13, as shown inFigure 3, and between that end of the clapper and the'pivot thereof is abracket 28 riveted to the side of the clapper. A bolt 30 isadjustablyheld in a threaded aperture 31 in the support 8 and a boss 32thereon and is held in any adjustment by a jam nut 33. A coiled spring34 on the bolt 30 exerts its expansive force between the head of thebolt and a horizontal part 35 of the bracket 28 through which the boltloosely extends.

Ba ling presses are provided with a device for retardingthe progress ofa completed bale on its way to the end of the press where it is 1 e0 7slowly longitudinally and takes up the slack v in the" wire with whichthe bale has been bound, as shown in dotted linesin'Figure 1.

The lower part of the lever 22 is close to the I bale so that theupperwire 36, as it is placed, encloses thelower part of the lever, as shownin Figure 1, and is tight enough to swin the lever in-the direction ofmovement of the ale. As th'e-lever swings onits pivot 20 the dog 25operates against the adj acent endof the clapper 17 and rocks the latteron its pivot 18 on the arms 11 and 16 on the support 8. The clapperrides up on the beveled end of the dog 25 and against the expansionofthe spring 27 until the clapper has been rocked to its limit, thelever 22 and the dog and clapper then being in the position as shown inFigure 5. Further movement of the lever disengages the dog and theclapper, so that the latter, by contraction of the spring 27 isinstantly rocked on its pivot 18 causing the opposite end of the clapperto strike the bell 13 with suflicient force to ring and so warn theoperator of the press that suflicient material has been fed into thebaling chamber to form a bale as 5.

It will be noted that the action of the spring 27 is contractile, andthe action of the spring 34 is expansive, so that the action of bothsprings is to hold the clapper 17 substantially horizontal and free fromcontact with the bell 13 until it is actuated by operation of the lever22 and the dog 25. When the clapper 17 is rocked by swinging motion ofthe lever the spring 27 forcibly expands by the rise of that end of thelever to which it is attached, consequently its contractile power ismaterially increased, at the same time the normal expansive power of thespring 84 is very much decreased, it therefore follows that with theinstant release of the clapper from the dog, the former, by the suddencontraction of the spring 27 snaps back with sufiicient force to causeits free end to strike the bell, then by the combined action of bothsprings the clapper is restored to its normal inoperative position.

After the dog 25 and clapper are disengaged the parts are as shown inFigure 6, the lever however is still being operated upon by the movementof the bale 4, the upper wire 36, holding the lever and actuating it,has been drawn taut. Dotted lines, in Figure 1, of the end of the leverindicate the limit of its movement by the bale. At this point the leveris free again and as it is loose on its pivot gravity swings it towardits normal position. As shown in Figure 6 the dog 25 has passed theclapper 17 and the latter is again in readiness for actuation; the doghowever is on the side of the clapper opposite from its operativeposition, and its return to normal position to actuate the clapper isaccomplished by the lever swinging a sufilcient distance to cause thedog to rock on its pivot on the lever so as to pass the clapper, asshown in Figure 7, after which movement the lever and the dog return tothe normal operative position shown in Figures 1 to 4 inclusive.

What I claim is- 1. In an alarm device for baling presses adapted to bemounted on a press, the combination of a support, a bell on the support,a clapper pivotally mounted intermediate its ends on the support, alever pivotally mounted intermediate its ends on the support andswingable by longitudinal movement of a bale, a dog pivotally supportedintermediate its ends on the lever and operating to rock the clapperwhen the lever is swung a predetermined distance and to instantlyrelease the clapper by continued swing of the lever whereby the clapperis caused to ring the bell.
